There was a link floating around about how the best way to construct a lineup. Basically, it's not that critical. But if a team is using OPS, which it suggested, then it basically recommends using the highest OPS guy to bat 2nd, the biggest power guy at 4th, then just fill in the rest 1-9 in order of OPS. So, day to day, the Twins don't really have it too far off, with one really big exception. Of all the Twins regulars, only Escobar and Suzuki are outperformed by Mauer in OPS. But I think the sky would open if people saw Mauer hitting 7th, so I'd maybe just move him to 5th or 6th. So one idea 4th-9th against a typical right hand starter would be 4-Sano, 5-Mauer, 6-Hunter, 7-Rosario, 8-Escobar 9-Suzuki. There are probably some other advanced stats that correlate better to run scoring than OPS, but OPS is better than AVG, OBP or RBI. Mauer probably shouldn't be hitting third. He doesn't strike me as having a big ego, so I don't know what the hold up is for moving him down. His past batting titles just aren't doing the team much good in the third slot right now.
